teven/bi_all_bs192_hardneg_finetuned_WebNLG2020_relevance

This is a sentence-transformers model: It maps sentences & paragraphs to a 768 dimensional dense vector space and can be used for tasks like clustering or semantic search.

Usage (Sentence-Transformers)

Using this model becomes easy when you have sentence-transformers installed:

pip install -U sentence-transformers

Then you can use the model like this:

from sentence_transformers import SentenceTransformer
sentences = ["This is an example sentence", "Each sentence is converted"]

model = SentenceTransformer('teven/bi_all_bs192_hardneg_finetuned_WebNLG2020_relevance')
embeddings = model.encode(sentences)
print(embeddings)
